Do you have any thoughts on the Grayl Geopress Water Purifier Water Bottle? I know you said you weren’t the biggest fan of the Ultralight Water Purifier Bottle from Grayl, and I was wondering if you had the same reservations about the Geopress. I was thinking of getting one for my bug out bag and killing two birds with one stone by getting a bottle and filter in one. I have an MSR Guardian, but would like something cheaper to have in my bag. Great article by the way…very informative and helpful!
